“…We expect lightning flash rate to correlate with CAPE and vertical wind shear based on previous studies that show a positive relation between CAPE and lightning flash rate (e.g., Williams et al 1992Williams et al , 2005Gilmore and Wicker 2002;Qie et al 2003). Previous work has also connected flash extent and vertical wind shear (Huntrieser et al 2008).…”

“…We calculated the lightning density per CAPE to investigate the impact of CAPE on lightning activity, and the sensitivity of lightning to changes in CAPE. Qie et al (2003a) calculated a similar parameter, but examined the lightning frequency in a select region as a function of CAPE to compare the sensitivity of lightning to CAPE in different regions. Figure 7 shows the monthly distribution of total CG lightning density per CAPE.…”

“…Climatological aspects of lightning activity can represent spatiotemporal patterns of deep convective activity, which can also act as effective indicators of climate change (e.g., Reeve and Toumi, 1999;Ma et al, 2005b;Zipser et al, 2006). Hence, lightning activity has been widely studied in different regions for a variety of purposes (e.g., Hidayat and Ishii, 1998;Altaratz et al, 2003;Christian et al, 2003;Qie et al, 2003aQie et al, , 2003bKandalgaonka et al, 2005;Ma et al, 2005a;Kuleshov et al, 2006;Rudlosky and Fuelberg, 2010). Research has demonstrated the apparent dependence of lightning activity on climatic and geographic conditions in different regions.…”

This study examined lightning activity and its relationship to precipitation and convective available potential energy (CAPE) in South China during 2001-12, based on data from the Guangdong Lightning Location System, the Tropical Rainfall Measuring Mission satellite, and the ERA-Interim dataset. Two areas of high lightning density are identified: one over the Pearl River Delta, and the other to the north of Leizhou Peninsula. Large peak-current cloud-to-ground (LPCCG) lightning (>75 kA) shows weaker land-offshore contrasts than total CG lightning, in which negative cloud-to-ground (NCG) lightning occurs more prominently than positive cloud-to-ground (PCG) lightning on land. While the frequency of total CG lightning shows a main peak in June and a second peak in August, the LPCCG lightning over land shows only a single peak in June. The ratio of positive LPCCG to total lightning is significantly greater during February-April than during other times of the year. Diurnally, CG lightning over land shows only one peak in the afternoon, whereas CG lightning offshore shows morning and afternoon peaks. The rain yield per flash is on the order of 10 7 -10 8 kg per flash across the analysis region, and its spatial distribution is opposite to that of lightning density. Our data show that lightning activity over land is more sensitive than that over offshore waters to CAPE. The relationships between lightning activity and both precipitation and CAPE are associated with convection activity in the analysis region. : Climatology of lightning activity in South China and its relationship to precipitation and convective available potential energy.

“…The understanding of lightning activity on the Plateau is still very limited so far. Qie et al [6] studied the characteristics of lightning activities in Naqu on the central Plateau by using Lightning Imaging Sensor (LIS) database and found that the flash activity showed a clear diurnal variation and was more sensitive to the solar heating on the plateau than in the same latitude nearby. In this paper, the spatial and temporal distribution of lightning flash activities on the whole Tibetan Plateau is studied by using the 8-year LIS/OTD database provided by Marshall Space Flight Center, Global Hydrology and Climates Change (GHCC).…”

We study the spatial and temporal distribution of lightning flash activity and its response to the thermodynamic characteristics on the Tibetan plateau by using the composite gridded lightning data from 1995 to 2002 observed by the satellite-based sensors, provided by NASA LIS/OTD Science Team in Marshall Space Flight Center. The result shows that the mean flash density on the Tibetan plateau was 3 fl·a −1 ·km −2 , and the maximum flash activity was on the central Plateau around (32 • N, 88• E) with a peak value of 5.1 fl·a −1 ·km −2 . The flash activity on the Plateau exhibited a seasonal variation and mainly occurred from June to August with a maximum flash activity period from late June to middle July. The diurnal variation of the maximum flash rate peaked during 14:00∼16:00LT with exceptions of the prominent high mountain region, which peaked earlier, and prominent low basins, which peaked later. The flash activity on the Plateau strongly depends on the ground thermodynamic characteristics, and a positive correlation between lightning activity and Bowen ratio and ground sensitive heat flux is found during the plateau monsoon season. The correlation coefficient is 0.7 and 0.6, respectively, and the Bowen ratio could be an indicator of lightning producing efficiency.
